Cast & Crew
While Dagwood Bumstead waits for his newly invented fireproof paint to finish cooking, he joins his son Alexander at a gymnasium that he and some other boys have made in a nearby barn. When short, bespectacled Rollo complains that no one will box with him, Dagwood volunteers, believing that he can easily beat the boy. To his surprise, Rollo is an excellent athlete and gives Dagwood a black eye. At home, Dagwood tests his invention and discovers that it works perfectly. The following day, when George Radcliffe, Dagwood's boss, announces that they will be bidding on a contract to build a new school, Dagwood suggests that they use his paint, but Radcliffe is skeptical. The following day, Dagwood intends to bring his paint to the office to demonstrate its effectiveness, but collides with the postman on the way out the door. Later, however, Dagwood tries to set a match to the handkerchief he used to wipe the paint off the mailman and Radcliffe is convinced. He then praises the paint to Forsythe, the president of the board of education, who asks for a demonstration on an actual building, and Radcliffe agrees to test the paint on his fishing cabin at the lake. When Dillon and Slack, partners in a competing construction firm, read an announcement of the test in the papers, they become worried about losing the contract. Using a phony name, Slack visits Dagwood's wife Blondie and pretends to represent a fire insurance company. Blondie eagerly shows him the paint, and he makes note of its color. He then offers to drive them both to the cabin. The next day, Slack switches Dagwood's paint with regular paint. When the house is set on fire in front of the mayor and school board members, it burns to the ground. With the help of Daisy, the family dog, Rollo finds the empty paint can where Slack discarded it and realizes that the house was painted with regular paint. Suspecting that Dillon and Slack are behind the switch, Rollo then suggests that Blondie get a job at the company and see what she can learn. At the company, Blondie overhears Dillon tell Slack that he intends to have Dagwood's paint analyzed and patent it for themselves. Blondie passes on the information to Radcliffe, who telephones Forsythe, but Dillon and Slack have already announced that they will demonstrate their fireproof paint. Rollo then suggests that he and Blondie switch paint just like Slack did, but Blondie is late arriving at the company, and is recognized by Slack. After tying up Blondie, Dillon and Slack successfully demonstrate Dagwood's paint. Blondie arrives just as the demonstration ends, having been released by the company's former secretary. When she plays a dictaphone recording of Dillon and Slack's conversation about the paint, Radcliffe gets the contract to build the new school.
